Deformation and fracture of high-temperature steels at different temperatures and loading rates
Charpy impact tests were conducted at different temperatures and loading rates. Temperature dependences of the crack initiation and propagation energies were determinedfor carbon steel 45, steels St. 3 and 15Kh2NMFA from the load-time curves obtained with due account of the impact test results. The...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Charpy impact tests were conducted at different temperatures and loading rates. Temperature dependences of the crack initiation and propagation energies were determinedfor carbon steel 45, steels St. 3 and 15Kh2NMFA from the load-time curves obtained with due account of the impact test results. The effect o f the loading rate on the temperature dependence o f the impact toughness was analyzed within the range from 1 to 4.4 m/s.
Выполнены ударные испытания образцов типа Шарпи при различных температурах и скоростях нагружения. Для малоуглеродистых сталей 45 и Ст. 3, а также для стали 15Х2НМФА определены температурные зависимости энергий инициирования и распространения трещин по диаграммам нагрузка-время, полученным с учетом результатов ударных испытаний. Проанализировано влияние скорости нагружения на температурную зависимость ударной вязкости разрушения в диапазоне скоростей нагружения 1...4,4 м/с.
